Guhring 9048870050000 Spiral Point Tap M5x0.80 Cobalt

Product Description

The GUHRING 9048870050000 is a spiral point tap designed for through-hole threading in steel and similar materials. Built from HSS-E cobalt for elevated heat resistance and tool life, it carries a plug chamfer and Ignator coating to reduce friction and extend performance in production environments. The tap cuts an M5x0.80 metric coarse thread to a 6H class of fit, meeting standard tolerance requirements for general mechanical assembly. With a 3-flute spiral point geometry, it pushes chips forward through the hole rather than backing them out, making it well-suited to CNC tapping centers and hand-tapping operations on through-hole features. Licensed machinists and toolroom technicians are the primary users of this tap.

This tap is intended for through-hole threading applications in steel workpieces where a metric M5x0.80 thread form is required. The plug chamfer provides a gradual thread start, making it appropriate for both machine tapping and hand tapping in production and maintenance settings. The Ignator coating improves lubricity and wear resistance, which is especially beneficial in high-cycle or semi-dry machining conditions. It belongs to GUHRING Series 4887 and carries a D3/D4 thread limit for controlled fit.

Key Features

• M5x0.80 metric coarse thread form, 6H class of fit for standard tolerance assembly
• HSS-E cobalt construction for improved heat resistance over standard HSS
• Ignator coating reduces friction and extends tool life in steel applications
• Spiral point geometry pushes chips forward, optimized for through-hole threading
• Plug chamfer for gradual thread engagement in machine or hand tapping
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for through-hole threading of M5x0.80 metric coarse threads in steel. Part of GUHRING Series 4887 with a D3/D4 thread limit and 6H class of fit.

Installation Notes

This tap should be installed and operated by qualified machinists or toolroom technicians familiar with tapping speeds, feeds, and cutting fluid requirements for cobalt tooling. Always secure the workpiece and ensure the tap is properly aligned before engagement to avoid tap breakage or thread distortion. Use appropriate tapping fluid or cutting oil for steel applications. Follow machine manufacturer guidelines for spindle speed and torque settings when used in CNC or manual tapping equipment.
